    What is it about a 383 that puts them in the 2000$ range all day long? You can pick up bbc's and 350's for alot less exspensive. Is it just that people think they are worth that kinda money? Or do they actually sell?

    gm never actually produced a 383 from the factory so essentially a 383 is a custom build, requiring machining work etc

    A 383 is actually a 350 sbc .30 over isn't it? Also aren't 383's actually a factory mopar engine?

    The 383 small block Chevy is a .030 over 350 with a 3.75" stroke crank. The factory 350 crank was 3.48". 383 Mopar is a completely different animal, and are really a dime a dozen compared to 440s.

    A 383 is normally a 350 block bored .030" over, then the crank is changed from a 3.48" stroke to one with a 3.75" stroke.

    GM does make a crate motor that is a 4.00" bore (no overbore) with a 3.80" stroke they call an HT383 made for truck applications.

    I was under the impression they cost 3 or 4k? I wish I could find one for 2k! haha or were you talking about used motors?

    Yep, looking on Craigslist all day long you can find them in the 1500-3000 range used.

    Factory blocks almost always require clearancing to fit that long a stroke inside them. That takes time and can't be done by a machine. Best comment from above: "because they are a custom build." Try one yourself from a junkyard block and you'll see how true that is.

    383 is a modification.If you bore a 350 say 30 over,you need to buy new pistons regardless.Back in the day getting a 350 iron crank reground at the machine shop was 100 bucks.Now you can buy a steel 383 crank(Scat,Eagle.etc.) for 200 bucks.You can get a good set of rods for under 200 bucks.New flexplate and balancer another 150 bucks.

    When you rebuild a 350,the 383 is a good bang for buck project.
